How to make a submerged cell phone usable again

It is a cell phone that most people in the world carry around with as much as they are now, but there is a danger that they will be submerged for various reasons, such as sudden rain, dropped to places such as toilets . In fact editing department two people were submerged.

If you let the mobile phone submerge, mostly you just give up, but there are many things that you can not give up for by reasons such as not backing up inside. Then I summarized what to do in that case. Since it is not certain that he will be healed correctly, at his own risk.

Details are as follows.How to Save a Wet Cell Phone - WikiHow

1. "Pull out the battery first"
Since there is a possibility of short-circuiting, it is necessary to be ahead of anything whether or not the battery pack is flooded.

2. "Remove moisture as much as possible"
Use towels and paper towels to peel as much water as possible. Then it is good to try 3 to 6 methods to remove moisture that entered the inside of the mobile phone.

3. "Immerse in alcohol"
Since alcohol has hygroscopic property, it is said that a method of immersing in alcohol and removing moisture may be effective. Moreover, if it is not about 70% alcohol which is usually sold, if you use about 95% of alcohol, the alcohol remaining in the phone will evaporate after removing moisture. By the way, when alcohol is used, there is a possibility that the adhesive etc melts.

4. "Put in a bowl of raw rice"
Putting raw rice before cooking in a bowl and putting a mobile phone in it in it will absorb moisture. Is it true?

5. "Warm cell phone"
It seems to be good to leave behind part of the cathode ray tube TV or CRT monitor and the part emitting heat for 2 to 3 days as a method of evaporating moisture seeped inside the telephone. That way, moderate heat will evaporate the moisture. There seems to be another way to put it in a moderately warmed oven all night, but it is going to be ridiculous if it fails.

6. "Place in front of air conditioner"
Since the wind of the air conditioner is basically dry, it seems that there is a high possibility of drying well even with warm air or cold air. It may be worth a try if you are using air conditioners at all times.

7. "Wait a couple of days and then turn on the battery and check it"
After trying methods 3 to 6, test the battery by putting the battery in a state where moisture is missing objectively, such as the inside of the display of the mobile phone is not cloudy. If this is not enough, it is only a matter of hoping for a slight hope and bringing it to the service counter again or give up.

* By the way note is as follows
· Do not put batteries in the middle of work as there is a risk of being short-circuited and completely disabled
· Since there is a risk of leakage, do not heat the battery
· Since the body may melt or burn, do not try to dry with high heat
· When removing moisture with alcohol, do not put the battery until the smell of alcohol disappears completely
· There is a possibility that parts will corrode due to mineral dissolved in water, even if all moisture escapes, there is a possibility of short-circuiting due to it

Even if you do just that, it seems that you have to keep backups of important data from day to day, considering that there is no guarantee that you can fix it certainly. Even if it can be used again afterwards, it seems there is a risk of parts being corroded and short-circuiting, so it seems only to keep in mind the change of the model even if it can be used.
